This project will teach you about sensors, data processing, and safety applications. It really is a hands-on way to learn electronics and programming while building a useful gadget. Get your Arduino ...

Insert the Arduino Nano and MQ-2 smoke sensor in the breadboard. Power up the sensor through Arduino and connect the A0 pin of the sensor to A5 of Arduino. Connect a buzzer and an LED in a parallel ...

I will attach all the schematics and the PCBs design for the project. I will start by doing the PCB design for the smoke sensor detector. Components: Arduino UNO; Power Supply; Smoke Sensor (MQ2) ...

MQ-2 Gas and Smoke Sensor Module – Parts. In most Arduino projects, the MQ-2 sensor is used to detect hazardous or flammable gas or smoke and hence this sensor is popular among beginners.Also these ...

Simply connect the Sensor's output to any digital pin on the Arduino and check for a high pulse; if the Arduino reads a high pulse, Gas has been detected; if the Arduino reads a low pulse, no Gas is ...

return val; } /***** MQRead ***** Input: mq_pin - analog channel Output: Rs of the sensor Remarks: This function use MQResistanceCalculation to caculate the sensor resistenc (Rs). The Rs changes as ...
